Is the 2nd E natural like the 1st E?
I asked a similar question earlier today:
And I was told that the 2nd time a note occurs in the same bar and same octave of an earlier note, it follows the same accidental.
But in this case, there is a vertical line separating the first two E's. Are they in different bars? Or are the double vertical lines (that separate 1. and 2.) bars?
